Hot brake/wheel on 1 side

Hi

Noticed this recently, even after a fairly brisk 20 minute drive from cold.

My left rear has a lot of hot air coming from it whilst the right has zero, could also hear a kind of ticking noise every few seconds once i pulled up, any ideas?

Its an E92 LCI 320d, been MOT’d and serviced recently and all was fine!

Caliper is sticking. Pretty common and needs to be taken care of or you’ll damage the rotor.

Could possibly also be a wheel bearing.

99% of time it will be caliper binding

Almost certainly the brake caliper sticking.
Fairly easy fix but do it immediately as it affects the braking and the heat build up could damage other components.

Most likely a seized caliper. I had that a while ago. Killed my discs.

Wheel bearing wouldn't get so hot and would make a groaning noise, especially around corners.
Like others have said, sticky caliper is most likely culprit. Either stuck piston or slide pins due to damaged seals.

I've seen it before. Not discrediting the caliper as the culprit, I agree, it's the most likely, just throwing out another possibility being the bearing.

Did anyone manage to find out what the fix was for this? I have the same problem

I recently had this, it was a sticking caliper. Unfortunately before I realised it was sticking it has dried out the bearing so going in for a new bearing next week. Caliper cleaned up (easy job) and treated to new discs and pads on the rears
